To all whom t may concern:

Be itknown that I, EMIL KLAHN, a citizen of the United States, andl a resident of Weehawken, in thecountyof Hudson and State of New Jersey, have invented certain new and useful Improvements in Gyroscopes, of which the` following is a, specification. y The invention relates'to gyroscopes; and more particularly to the manner of supporting and driving the rotatable or gyroscopic member thereof.

It has for its object to simplify the mounting and driving of the said rotatable member withoutdestroying the necessary freedom of oscillation of its` axis of rotation; and, furthermore, to provide a force, other than the @attraction of gravity,V to act` on such member. v

A further object of the invention consists in so effecting the transmission of the gyroscopic property of the gyroscope member to another member or members, which it is deu sired the force should aliect, that such transmitted force may be entirely suspendedor varied' as desired, and also instantaneously applied thereto. y

'llie nature of the invention will best be 'understood when described in connection with the accompanying drawings, in Wliiclim Figure 1 is a front elevation of the improved gyroscope. Fig. 2 is a plan thereof. Fim-3 is a vertical section taken on the line n i Y 3-13, 111g. 2, but omitting the motor and.

base. l

Referring to the drawings, 10 designates any suitable base for an electric `or other 'a sleeve 15 thereof extending in'wardly over the said driving shaft and within thc core of electro-magnet v13, whereby said. disk becomes strongly magnetizmh as for the Vpurpose hereinafter set forth. f

rlhe outer end of the shaft lQ'is shown of reduced diameter, providing a.v shoulder ,16.

About this reduced portion pivotallymounted theI rotatable gyroscopic member 17 and iii such a manner as to have perfectly free oscillation, limited, of course,.but sufficient to allow it three degrees of freedom of rotation. Such universal joint between the gyroscopic mein-ber 17 and the shaft l12 may be effected in the following manner. As shown,v a ball 18 is mounted about the reduced portion of the Shaft 1:2, being held to the shaft by a screw 18', and abuts the shoulder 1G. The ball is centrally litted tothe web of the member' 17 bynieans of a lower plate 19, which is of magnetic materiahand an upper plate or cap 20, `both of which plates are suitably secured to the said web. The outer surface of plate l9,is arranged somewhat above the upper surface of the disk 14, leaving a slight air gap 21 between. The member 17 thus remains perfectly free to oscillate, and consequently a free oscillation of its axis 'of rotation is possible, the said rotation of the member being accomplished through the action of disk lltupon the plate 19., The magnetism of the disk 14 -provides furthermore, for a force,l other than that due to gravity, to act upon the member 17 whose gyroscopic property is, moreover, transmitted through this medium to the shaft 12-and from it to such 'parts as it is desirable thatthe force shall affect. The gyroscopic 'force may be regulated, or even rendered entirely inoperative, by Silitably controlling rthe excitation of magnet 13 by means of, foil example. switch 13. Upon closing` the said switch, lthe gyroscopic property is instantaneously, transmitted to the member or members it is desired that the force should affect. l

The manner herein set forth of effecting the connection between shaft 1Q and member 17 to allow, within the hereinbefore mentioned limitation, perfect freedom of rotation of the lutter affords a convenient construction, but l do not desire to be understood as restricting myself to such particular construction. for it is evident that the connection may he eli'ccted inotherways.
